I recently purchased a bottle of Macallan 30 year old for a gift. The person who i am gifting it to is a macallan fan by heart and only drinks macallan. He has had the 15, 18, 21 and i think the 25. I dont know if he had the 30 or not. Do you think he will be pleased with it. What does it taste like compared to the other ages? I just dont wanna make a $1000 mistake.
